SPECIFICATION forming part of Letters Patent No. 429,040, dated May 27,1890'.

Application filed March 21, 1890 Serial No. 344,818. (No model.) I

To aZZ whom it may concern.-

Be it known that I, GEORGE E. LUM, of Stamford, in the county ofFairfield and State of Connecticut, have invented certain new and usefulImprovements in Saw-Greasers; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it pertains to make and useit, reference being had to the accompanying drawing, which forms part ofthis specification.

My invention relates to an improvement in saw-greasers; and it consistsin the particular construction hereinafter described, and particularlypointed out in the claim.

The object of my invention is to provide a device of the constructionhereinafter described for greasing saws and applying tallow to tools andsurfaces of all kinds, and by means of which the tallow can be directlyapplied to and rubbed upon the saw by the device itself and without anyunnecessary waste or the mechanic getting his hands soiled each time thetallow has to be used.

The accompanying drawing represents a longitudinal section of a devicewhich embodies my invention.

A represents an open-ended tube, which is made of wood, metal, or anyother suitable material, and which is provided with an internal threadat one end and an external thread at the other. threads of the tube arenot formed entirely through it, so as to leave a plain or smooth portionE, since it is desirable to have as few internal threads as ispracticable in a device of this character, as will hereinafter appear. Afollower or plug Bis provided for forcing out the tallow C, and thisplug has its outer end formed into a handle, its central portionscrew-threaded, and its inner end provided with the reduced port-ion G,which is circular in form and fits snugly the smooth portion E- of thetube and made of a length about equal to the length of the said portionE, whereby when the screw-threaded portion of the follower has reachedthe limit of its movement upon the internal threads of the tube Theinternal screW- the projecting portion G is at the outer end of thetube. By means of this construction it will be seen that thescrew-threaded portion of the followeris not brought directly in contactwith the tallow until it has been displaced by the projection G, thusmaking it easier to force the tallow out when hard and avoiding theworking of the tallow back to the rear end of the tube, as is the casewhere the tallow has become soft and is allowed to extend to near therear end of the tube. and in direct contact with the screw-threadedportion. An internally-screw-threaded cover D is applied to the externalthreads upon the outer end of the tube, which protects the tallow fromdirt and dust when not in use.

In order to adapt this device to be used to apply the tallow directly toand rubbed upon the saw by the device itself, it is necessary that it beso constructed that the entire end of the tube will be exposed when thecover is removed and the entire surface of the tallow projected beyondthe tube, so that the tube will not come in contact with thecutting-edge of the saw or other tool while the tallow is being applieddirectly from the device to the tool; hence it will be seen that by adevice of this particular construction I am enabled to rub the tallowdirectly upon the tool without the use of a rag or other similarspreading device. It is only necessary to force the tallow by means ofthe plug just far enough beyond the end of the tube to grease thearticle to which it is to be applied. By means of the construction hereshown it is only necessary for the mechanic to remove the cover. Then hecan grease the saws, tools, and surfaces of all kinds without theslightest trouble or liability of soiling his hands in any respect.

Having thus described my invention, I claim In a device for the purposehereinbefore described, the combination of an open-ended tube having itsouter end externally screwthreaded and its inner portion internallyscrew-threaded, and its internal outer end left smooth, a followerhaving its central portion externally screw threaded, its outer endformed into a handle and provided at its in- In testimony whereof Iaffix my signature ner end with a reduced smooth portion of a inpresence of two Witnesses. length and diameter abou t1 equal to thelength and diameter of the internal smooth portion of GEORGE the tube,whereby the screw-threaded por- \Vitnesses: tion is not directlyincontact with the tallow, FRANK MILLER,
